Bummer.  I was a bit quick.  Was this the bit about whether a struct
(at least the first 8 words) is passed in registers?  I believe there
was an issue that SYSV passed the first 8 words in registers, while
AIX passed the whole struct in memory by reference.

BTW, I forgot to say, thanks for pitching in, Matt.
